About us

Hexa is the first product designed by Koolmask, a Seattle-based tech start-up founded by Edward and his son Luke.      

When living in Asia, Luke suffered from severe allergies and asthma caused by air pollution.  Like most kids, he loves to play outside, but had to wear a facial covering for all outdoor activities.  However, Luke could barely keep the mask on for 10 minutes due to the discomfort caused by the excessive heat, moisture, and restricted breathing.  Feeling frustrated and restricted, Luke wanted to have a mask that felt cool, looked cool, and would also protect him from air pollution.

They looked hard, but could not find an adequate mask on the market, so they decided to develop their own.  After two years of hard work and help from family and friends, Hexa has risen from an idea to a product, with multiple pending international patents.

Luke and Edward hope Hexa will help everyone suffering from the effects of air pollution enjoy normal, active lives.
